PlatePreparation 1.Dilute the capture antibody to the working concentration in CBS. Immediatelycoat a 96-well microplate with 100uL per well of the diluted captureantibody. Seal the plate and incubate overnight at 4C. 2. Aspirate eachwell and wash with at least 300ul wash buffer, repeating the processtwo times for a total of three washes. Complete removal of liquid at eachstep is essential for good performance. After the last wash, remove anyremaining wash buffer by inverting the plate and blotting it against cleanpaper towels. 3. Block plates byadding 300ul ofblocking buffer to each well. Incubate at room temperature for a minimum of1hour. 4. Repeat theaspiration/wash as in step 2. The plates are now ready for sample addition. AssayProcedure 1.Add 100 ul ofsample or standards in sample dilution buffer per well. Seal the plate andincubate 2 hours at room temperature. 2.Repeat the aspiration/wash as in step 2 of plate preparation. 3.Add 100 ul of thedetection antibody, diluted in antibody dilution buffer, to each well. Sealthe plate and incubate 1 hour at room temperature. 4.Repeat the aspiration/wash as in step 2 of plate preparation. 5.Add 100ul ofStreptavidin-HRP to each well. Incubate for 1 hour at room temperature. 6.Repeat the aspiration/wash as in step 2 of plate preparation. 7.Add 200 ul ofsubstrate solution to each well. Incubate for 20 minutes at room temperature (ifsubstrate solution is not as requested, the incubation time should beoptimized). Avoid placing the plate in direct light. 8.Add 50ul of stopsolution to each well. Gently tap the plate to ensure thorough mixing. 9.Determine the optical density of each well immediately, using a microplatereader set to 450nm.
